Scirocco Central

A slightly odd one - When I adjust the 2 central fans to direct them downwards, they keep reverting to pointing at the roof! Does this happen to anyone else? i find it really strange!

YES!!!! Same problem. This happens for me only in the summer when i get warm in the car. Once cold starts blowing through the vents they regain "grip" and work as normal... Still its kinda of annoying, thought about talking to the service shop about I but never got around to it and now its cold and i can reproduce the problem
